P-61 Black Widow
The Northrop P-61 Black Widow was the largest and heaviest fighter aircraft to serve with the USAAF during the Second World War, and the first American aircraft specifically designed from the outset for the night fighting role. The service life of the Black Widow extended into the immediate postwar period, and replacement of the Black Widow by F-82F Twin Mustangs night fighters began in early 1948. Most Black Widows were out of operational service by early 1950.
